OILER FAOR LCOMOTIVES.

SPECIFICATION forming` part of Letters Patent No. 253,579, dated February 14, 1882.

' Application filed Octoberl, 1881. (No model.)

To all whom fit may concern:

Be it known that we, ALvA O. BROOKS and PHILTP A. BOWEN, both of Milwaukee, in the county of Milwaukee, and in the State of Wiscousin, have invented certain new and useful Improvements in Oilers for Locomotives, Snc.; and we do hereby declare th at the following is a full, clear, and exact description thereof.

Our invention relates to oiling devices for locomotives and other machinery while in motion, and will be' fully described hereinafter.

The figure in the drawing is a longitudinal vertical section of our device, in which A is au oil-cup, having avalve-chamber, A', that screws into an oil-reservoir, B, and this rcservoris in turn screwed into another valve-chamber, C, to which is screwed yet another valve-chamber, D. The chamber C opens up into the reservoir B through its stem b, and has threaded branches c c, connecting with pipes C C', leading each to one of the steam-chests of the cngine, (not shown,) and these pipes are opened and closed by valves d d, the stems of which project from wheels E. The chamber D connects the chamber C with the boiler, so that steam therefrom passing` through the chamber D and thechamberC,wl1ich latter hasa vertical opening through its center, may enter pipe F,

When the engine is at rest and steam shut ott', the valves may be oiled by closing valve G and opening valves H and d d. Then the oil will empty from cup A into reservoir B, and thence How through chamber O into pipes C and to the steam-chest; but when it is desirable to oil up while steam'is on, the reservoir B must he lled from cup A, after which valves H and t' must be closed and valves l el and G opened. Thereupon steam will rush 'into the reservoir B through pipe F and force all of the oil from the reservoir into the steam-chests through pipes C.

Our oiler, as shown in the drawing, is double, so as to feed out to both steam-chests; but we may construct them single, and in this case we would dispense with chamber D and the opening through the center ot chamber C and join pipe F to one ot' the branches c of chamber C, and to this branch we would attach, instead of an oil-pipe, a steam-pipe leading from the boiler, provided with a valve or stop-cock.

What we claim as our invention, and desire to secure by Letters Patent, is-

The combination of oil-cup, reservoir having' vent, the valve-chamber C, steam-inlet'and oiloutlet, and valves or stop-cocks, as set forth.

In testimony that we cla-im the foregoing we have hereunto set our hands this 24th day ot 65 September, 1881.

ALvA o. BROOKS. PHILIP A. BOWEN.
